Some sensors MAY actually work. This does not discard what i wrote before (I tested them all), but: For some reason some of the sensors gives invalid response to ‚Power supply’ command. They always respond as they are parasite-powered. Some devices (ex. mine) do check that and reported them as invalid. However I tested all ‚Invalid’ with osciloscope. Some of them gave some response, so i took the deeper test.
If you’re planning to order cheap DS18B20 sensors from AliExpress – keep in mind that irrationally low price (less than $0.8 / pc) smells really fishy.
Manufacturer price for 1k is $1.18.

Some time ago AliExpress (and probably others of their family) has simplified their search engine, removing some useful search options like:
- Sorting by price per piece / lot
- Selecting maximum quantity
- Showing price per piece
Although they are removed from the search panel, they are still valid and correctly parsed if added to URL.
To get those options, please append following parameters to URL. They are separated by & character:
|| URL Parameter
|Show Price Per Piece
|Maximal quantity in lot
|Minimal quantity in lot
To get lowest price per piece simply combine: „Show Price Per Piece” + Order by Lowest Price + (optionaly) Maximal quantity
